BALlNG-PRESS.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Appli ti fil d August 24, 1905. Serial No. 275,592-

To all whom it may concern.-

Be it known that I, JOHN W. REYNOLDS, residing at Erin, in the county of Houston and State of Tennessee, have invented cer tain new and useful Improvements in Baling- Presses, of which the following is a specification.

This invention relates to certain new and useful improvements in baling-presses; and it particularly relates to that class of presses known as hay and straw baling-presses, although I desire it understood that it can be used in connection with any reciprocating plunger-presses either for baling hay, straw, cotton, or other material.

In its generic nature my invention comprises a double-cam driving mechanism for reciprocating the plunger to compress the material, which driving mechanism is so arranged that the leverage exerted on the re ciprocating plunger is increased as the pressure against the piston increases, so as to compensate therefor.

In its more detailed nature the invention comprises a drive mechanism consisting. of an S-shaped double cam, means for turning said cam, means cooperatively connecting said cam with a reciprocating plunger, means for always holding the plunger in engagement with a cam, and means carried by the cam for releasing the plunger during every half-revolution.

Primarily my invention has for its object to provide a device of the character stated of a very simple and effective construction which can be easily and cheaply manufactured and which can be attached to any reciprocating plunger-press and will readily and eflectively serve its intended purposes.

With other objects in view than have been heretofore enumerated the invention also comprises certain novel construction, combination, and arrangement of parts, all of which will be first described in detail and then be specifically pointed out in the ap pended claims, reference being had to the ac comp anying drawings, in which- Figure 1 is a perspective view of my inven-- tion as applied for use. Fig. 2 is a top plan view thereof. Fig. 3 s a vertical longitudinal section of my invention, showing the position of the parts just after the plunger has Fig. 4 IS a horizontal section on the line 4 4 of Fig. 3 looking in the direction of the arrow. Fig. 5 is a detail perspective view of the cam-engaging end of the plunger. Fig. 6 is a detail per- I spective view of the cam member.

Referring now to the accompanying drawings, in which like numerals of reference indicatelike partsin all of the figures, 1 designates the baling-chamber, in which the piston 2 is reciprocally mounted, all of which may be of any approved construction, as the same per se forms no part of my present invention. The piston 2 has the usual plunger-arm 3, as shown.

4 designates a beam connecting the balingchamber frame with a base 5, upon which a frame 6 is mounted, and the frame 6 includes a pair of parallel bearing-arms 7 7, spaced apart and provided with bearing portions 7 7, as shown, the lower arm 7 being spaced above the beam 4 fora purpose presently explained.

8 designates a shaft mounted in the hearing 7 7 a of the arms 7 7, which shaft carries a double or S cam 9 at its lower end and a sweep-lever 10 at its upper end, to which the swingletree 1 1 is attached to enable the shaft 8 to be turned by horse-power. The cam 9 is substantially an S shaped cam and comprises the double-cam portions 9 9", respectively, which are separated at their adjoining ends to leave a passage 9 of su'llicient width to permit passage of the piston-rod 3. The piston-rod 3 has a friction-roller 3 at its free end for engaging with the cam portions 9 9 as shown.

13 designates a cross member secured to the beam 4, having an abutment 13 to prevent the piston-rod 3 from moving laterally in one direction, and the piston-rod is nor mally held against the abutment 13 by a spring-arm 14, carrying a friction-roller 14:, which engages the piston-rod 3, as shown.

15 designates a spring member secured to the abutment 13 and to the piston-rod 3 to normally move the piston in the direction of the arrow.

So far as described, the manner in which my invention operates will be best explained as follows: Motion is imparted to the sweep 10 in the direction of the arrow, which causes the outer end of the cam-section 9 to engage the friction-roller 3 and move the piston in a direction opposite to the indicatingarrow.

As the sweep-arm moves in the direction indi-' cated the piston 2 will be forced in to compress the bale, and as the halo is becoming compressed it takes more power to compress the same toward the finish of the stroke of the piston than at the beginning thereof, and

this is compensated for by the arrangement of the cam-sections 9 9 which move the pis ton-rod, withits roller 3*, toward the axial line of the shaft 8 as the piston 2 is moved inward to compress the bale, thus giving increased leverage as the bale becomes compressed. When the friction-roller 3 has rolled around one cam-section 9 and reaches a position in alinement with the shaft 8, the same will come in alinement with the passage 9 and be released from the cam by the spring 15, which moves the piston-rod 3 in the direction of the arrow to the limit of its movement in such direction, when it is ready to become engaged by the second section 9 in the cam member 9 and move back to compress the material again.

16 designates any suitable bufferfor receiving the impact of the piston-rod 3 as it is released from engagement with the cam 9.

By making the plunger 3 laterally movable and by providing the spring 14 and roller l4 as shown in the operation of my invention the lateral strains on the plunger 3 are counterbalanced, and, furthermore, by reason of such arrangement of parts and by reason of the S-shaped cam the leverage is varied properly so that the strain on the.

horse is maintained nearly even during the entire travel of the sweep-arm 10 around its fulcrum, Whereas should the plunger 3 be not laterally movable, but merely longitudinally reciprocable, there would be considerable lateral strain on the plunger, and the greatest power would have to be applied during the eginning of the stroke of the plunger from the position shown in Fig. 4, and it would take more power to start the plunger from left to right in Fig. 4 were it not laterally movable than it takes when the plunger is laterally movable, as shown, since the lateral strain in starting the plunger is practically eliminated by the arrangement shown in the drawings.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation, and many advantages of my invention will be readily understood by those skilled in the art to which it appertains, and I desire to say that many slight changes in the detailed construction, operation, and arrangement of parts may be made without departing from the scope of the invention or the appended claims.
